Consider the following list of gases:
H2, SF6, SO3, HI, C2H4
A) The gas most likely to dissolve in water as a result of chemical reaction is and the gas most likely to dissolve in water because of strong intermolecular interactions is .

Explanation:

Molecules which are either polar in nature or contain a polar covalent bond are able to dissolve in water. This is because like dissolves like.

For example, is a polar covalent compound and when it is dissolved in water then its reaction is as follows.

This shows that a chemical reaction will take place when is dissolved in water.

Also, HI is a polar covalent compound and it will readily dissolve in water as hydrogen iodide (HI) is a polar covalent molecule.

On the other hand, , , and does not dissolve in water as all of these are non-polar covalent compounds.

Thus, we can conclude that the gas most likely to dissolve in water as a result of chemical reaction is and the gas most likely to dissolve in water because of strong intermolecular interactions is HI.
